Stainless Steel Welded Frame Assemblies for Industrial Equipment
Material: SS304 / SS316L Process: TIG Welding + Fabrication Industry: Industrial Equipment
Custom TIG-welded frames, machine bases, equipment enclosures, and support structures — built from SS304/SS316L to your exact drawings. Full penetration welds. Dimensional accuracy down to ±0.5 mm. Components are finished and ready for direct assembly line integration.
Why Industrial OEMs Choose Conwhole
| Capability | Detail |
|---|---|
| 🔩 Certified TIG Welding | Our welders are all certified to the ISO 15614 standard. All welds meet the requirements for full penetration, porosity is kept within industry-accepted limits, and the appearance of the welds on all joints is consistent. |
| 📐 Precision Jigging | Custom fixtures ensure consistent frame geometry. Even in complex multi-joint assemblies, overall dimensional tolerances can be maintained within ±0.5 mm. |
| ⚙️ Integrated Post-Weld Processing | We offer full-process surface treatment services including grinding, passivation, electrolytic polishing and powder coating. Our one-stop solution saves you the trouble of working with third-party suppliers. |
| 📏 Batch Quality Control | Every production batch begins with a comprehensive dimensional inspection of the first unit. We conduct welding inspections throughout the production process and provide a detailed final quality report. |

Frequently Asked Questions
What welding standard do you follow?
Our welding procedures comply with AWS D1.6 (Stainless Steel) and ISO 15614. We can provide WPS and welder qualification records upon request.
Can you weld stainless steel to carbon steel?
Yes. Using appropriate filler metals, we can join stainless steel to carbon steel assemblies. Contact us with your specific material combination.
How do you control distortion on large frames?
We use sequenced welding techniques, fixturing to restrain movement, and stress-relief measures where needed. For high-precision frames, post-weld machining is available.
Do you offer assembly of components onto the frame?
Yes. We can integrate brackets, hinges, mounting plates, casters, and hardware before shipping — reducing your final assembly time.
What finish do you recommend for food-grade applications?
For food processing and pharmaceutical use, electropolishing or #4 brushed finish provides a smooth, non-porous surface that meets hygienic standards.
